Mite population dynamics on different grape varietieswith or without phytoseiids released
In a three-year study, mite populations were monitored in two vineyards, each having two grape varieties with different leaf hair density. In both vineyards native phytoseiids were present: Amblyseius andersoni in one vineyard, and Phytoseius finitimus in the other. The economically important predators Kampimodromus aberrans and Typhlodromus pyri were released in both vineyards in order to stud...

متن کاملErinea formation on Quercus ilex leaves: anatomical, physiological and chemical responses of leaf trichomes against mite attack.
Structures on the surfaces of leaves, such as dense layers of non-glandular trichomes, strongly affect phylloplane mite activities. On the other hand the feeding of eriophyoid mites on leaf surfaces can cause hyperplasia of leaf trichomes (erinea formation). In many cases the hyperplasia is accompanied by the accumulation of pigments within trichome cells, causing an impressive red-brown colour...
متن کاملPhytoseiidae in European grape (Vitis vinifera L.): bio-ecological aspects and keys to species (Acari: Mesostigmata).
The family Phytoseiidae includes many species of predators involved in the control of mite pests of crops all over the world. In European vineyards, these natural enemies play a key role in plant protection as their presence usually makes the use of acaricides unnecessary. Each species has its specific biological features. It is thus of great interest to identify the species reported on grape, ...
متن کاملRole of supplemental foods and habitat structural complexity in persistence and coexistence of generalist predatory mites
Plant traits can influence the interactions between herbivore arthropods and their natural enemies. In these interactions generalist predators are often present, preying on herbivores and also on other arthropods in the same trophic guild. Variation in the strength of intraguild predation (IGP) may be related to habitat structural complexity and to additional resources outside the narrow predat...
